Does this also happen while copying?
The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. Use the automated tool from the printer control panel to clean the printhead.
CAUTION:Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.
On the printer control panel, press Setup.
Press the down arrow button
to select Tools, and then press OK.
Press the down arrow button
to select Clean Printhead, and then press OK.
If the print quality is unacceptable, perform another printhead cleaning.
NOTE:
If the printhead is badly clogged, wait 30 minutes, and then clean the printhead again.
Try to print again.
